Selection of membership functions(MF)for a fuzzy logic controller(FLC)is an iterative and a time consuming task. This paper describes the use of genetic algorithm(GA)searcj strategy for optimizing MFs of antecedent and consequent variables of an FLC that has been used for controlling the level of water on real time basis in a laboratory scale pilot plant. For the simulation of GA integral time sqare error(ITSE),has been used as the fitness function.
